unmarkiertes

Unmarkiertes is a German adjective meaning unmarked or unlabeled. It is formed with the prefix un- added to the past participle markiert and declines like a regular attributive adjective. In neutral singular usage before a neuter noun, the form is unmarkiertes, as in ein unmarkiertes Dokument or das unmarkierte Dokument. In plural, unmarkierte Dokumente. Predicative use typically uses unmarkiert, as in Das Dokument ist unmarkiert.

In linguistics, unmarkiert describes a form that carries no explicit morphological marking for certain grammatical categories, such as case, number, tense, or mood. The unmarked form is often taken to be the dictionary or lemma form. For example, in many languages the bare infinitive or base form of a verb is considered unmarked for person and number, whereas finite forms show agreement. The concept helps describe how languages encode information through marking versus relying on context or other elements.

In data science and machine learning, unmarkiertes data or unmarked data refers to unlabeled data without category or target labels. Such data are used in semi-supervised and unsupervised learning approaches, where models learn structure or representations from the data itself rather than from explicit annotations. The term highlights the contrast with labelled data, which provide supervised guidance during training.

Usage notes: unmarkiertes is specific to neuter singular attributive positions; other endings exist for different genders, cases, and numbers. The term is common in linguistic and technical contexts and is understood within general German grammar as well as in German-language technical literature.
